TechTool Pro 9.5 goes above and beyond the basic diagnostics to keep your system running like a dream. It even goes as far as testing your motherboard, which no rival tool can do. But that's not all. Test everything from the sensors to the fans, and everything in between. Even create a bootable diagnostic device to test in the field. Whether you own a personal Mac or a whole fleet of business machines, TechTool Pro will catch problems before they start.
